使用Boto發送針對MTurk命中的SQS通知

Question

我正在嘗試為使用Boto創建的MTurk HIT設置SQS通知。 我能夠創建HIT類型，使用該類型創建HIT，創建SQS隊列，以及對隊列進行讀寫操作。 我還寫了命令（我認為）將為給定的HIT類型設置通知。 但是沒有發送通知。

知道發生了什么嗎？

Answer 1

您應該在SQS的AWS控制台上進入自己的隊列，並添加新權限：

效果：允許

校長：arn：aws：iam :: 755651556756：user / MTurk-SQS

動作：SendMessage

稍后，您應該使用首選通知和隊列的URL構建HITType。

這樣，當您在mturk上創建HIT請求時，Amazon Mechanical Turk的唯一有效用戶“ MTurk-SQS”會將通知消息從mturk requester.sandbox帳戶發送到SQS隊列。

您可能需要從MTurkR的Notifications中查看這些步驟。

Answer 2

如果您仍在為此苦苦掙扎，則需要在SQS中設置一些權限，以允許MTurk向其發送消息。 它們在這里描述：在這里輸入鏈接描述
